How to solve for joules
WebHowever, there is a conversion factor between L·atm and the common unit of work, joules: 1 L·atm = 101.32 J. Using this conversion factor and the previous equation for work, we can calculate the work performed when a gas expands or contracts. ... We can start with the equation for q, but now different values are given, and we need to solve ... WebAnd that's gonna equal, if you calculate all of this in this term, multiply the charges, divide by .12 and multiply by nine times 10 to the ninth, you get 0.6 joules of electrical potential …

WebIn classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per … WebAug 27, 2024 · Multiply watts by seconds to get joules. A 1 Watt device consumes 1 Joule of energy every 1 second. If you multiply the number of watts by the number of seconds, you’ll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.
WebSince work is energy, it has units of Joules (where 1\,\text J= 1\,\dfrac {\text {kg} \cdot \text m^2} {\text s^2} 1J = 1 s2kg⋅m2 ). You may also see other units used, such as atmospheres for pressure and liters for volume, resulting in \text L … WebIn other words, the change in kinetic energy of a body is equal to the amount of work done on that body. In general, the formula for the kinetic energy of an object is: KE = (1/2) …
WebFor the kinematic way i get v^2=196 and for energy way as sal stated we get v^2= 200 now i realise the difference is not huge with V=14ms/s for the kinematic way and V=14.14m/s for the energy way, but why does the difference exist if both methods can determine the same results? • ( 2 votes) Janne Valkila 5 years ago WebVery often, we choose U = 0 at the beginning, or maybe at the end, but in this type of question, we usually use the formula for PE that he gives us, U = k*q1*q2/r, which means that U only equals 0 when the two charges are infinitely far apart (r = infinity).
